  • Method and apparatus for producing a breathable coated fabric
    Patent number: 5322729
    Abstract: A method and apparatus for producing a breathable coated fabric is disclosed. The method involves coating a fabric substrate with a resin then opening pores in the resin by directing a flow of air through the fabric substrate and resin coating. The pores provide breathability of the coated fabric and allow for a vapor or moisture transmission rate about ten times that of a resin coated fabric without pores.
